Q: I suffer from renal failure. The doctor has forbidden me from performing Sawm (Fast), as it affects my health negatively and I cannot endure it. He decided that I should be treated by dialysis twice a week. I have undergone dialysis for a month and a half. Later I saw another doctor in Riyadh, who prescribed medication for me and diet. I eventually recovered, all praise be to Allah, but I broke my Sawm in Ramadan for three years. I performed Sawm this year with difficulty, as I consulted a doctor who recommended me to perform Sawm for ten days and then return to him to determine whether I could continue Sawm till the end of the month or break it. When I came back to him, he told me to continue performing Sawm till the end of the month. I hope you will advise me concerning the days in which I did not perform Sawm. Should I make up for the missed days of Sawm in the previous months of Ramadan, although I paid Kaffarah (expiation) for each month? If it is obligatory to make up for them, should I make up for the three months in one year or only a month per year? May Allah safeguard you.
